    A Social Approach to Environmental Sustainability: The Nexus Well-Being, Tourism, Digitalization and Renewable Energy in Scandinavian Countries
    (Wiley, 2025) Isik, Cem; Ongan, Serdar; Aydin, Buket; Aydin, Rahman; Imamoglu, Ilyas Kays
    This research explores the impact of subjective well-being (SWB) on CO2 emissions in Scandinavian countries based on the need to analyze the effects of social indicators shaping environmental sustainability. The study aims to introduce the Welfare-Based SWB approach to the literature by expanding the classical Environmental Kuznets Curve (EKC) hypothesis with the social welfare dimension. SWB is considered in this study to be a social reflection and indirect measure of economic growth, which is the core determinant in the classical EKC hypothesis. The second-generation cointegration test, the Durbin-Hausman, and AMG long-term forecasting methods were used in this context. According to the empirical findings, SWB and digitalization increase carbon emissions, while tourism revenues and renewable energy consumption reduce emissions. The findings indicate that the classical EKC hypothesis is not confirmed and, similarly, an increase in social welfare (SWB) does not automatically lead to environmental improvement. Therefore, policymakers should develop social policies that will increase environmental sensitivity along with an increase in welfare.

    Does Climate Change Vulnerability Cause Energy Vulnerability in Sustainable Development?
    (Wiley, 2025) Isik, Cem; Ongan, Serdar; Kuziboev, Bekhzod; Imamoglu, Ilyas Kays
    Climate change and energy security are two fundamental vulnerability areas that interact with each other and hold critical importance for sustainable development goals. This research aims to fill the research gap by investigating the effects of climate change vulnerability (CCV) on the energy vulnerability (EV) relationship, which has not been adequately addressed in the literature, using a large panel dataset covering 74 countries and employing various methodological approaches (MMQR, PLFC, DID). The results of the MMQR model indicate that CCV increases EV across all quantiles. According to the results of the PLFC model, it is revealed that CCV on EV varies depending on the economic development level of countries. This effect is higher in low-income countries. The study also employs the DID model to examine the impact of China's foreign energy investments on countries' EV. According to this model, China's fossil-based energy investments, particularly those in the energy sector, increase the EV of countries. While economic development reduces EV across all quantiles, financial development reduces it in the lower and medium quantiles (25% and 50%); urbanization reduces it in the medium and higher quantiles (50% and 75%). All results show that the interaction between EV and CCV is a multidimensional and dynamic process. Accordingly, policymakers should develop integrated strategies that consider environment and energy policies, economic development, investment type, and environmental risks. Lastly, policymakers should consider energy investments from China not only as a tool for their country's economic growth, but also in terms of energy security and sustainability.

    Economic complexity and energy vulnerability: Does ESG performance matter?
    (Taylor & Francis Inc, 2026) Ongan, Serdar; Kuziboev, Bekhzod; Makhmudov, Samariddin; Matyakubova, Aziza; Imamoglu, Ilyas Kays; Aydin, Rahman; Isik, Cem
    Energy vulnerability is a critical concern for achieving energy security and meeting the SDGs. However, the role of economic complexity, which represents a country's production and export diversification, in energy vulnerability has been largely neglected in the literature. This study fills this gap by examining the impact of economic complexity on energy vulnerability for 69 developing countries over the period 2000-2019. For this purpose, MMQR and various instrumental variable (IV) estimation techniques (IV-Quantile, 2SLS, Lewbel, and Kiviet) were used. In addition, ESG indicators were included in the model as instrumental variables to address potential endogeneity issues between economic complexity and energy vulnerability. In doing so, the ESG indicators are also included in the model as instrumental variables to control for the endogeneity of economic complexity. Empirical findings show that economic complexity is associated with lower energy vulnerability across all quantiles. These results reveal that countries with diversified economic structures (higher economic complexity) may be more resilient to energy shocks. Therefore, developing countries should focus on structural reforms and improve their ESG performances to reduce energy vulnerability. In terms of control variables, financial development, digitalization, and human capital are associated with lower energy vulnerability, whereas increases in natural resource revenues are sometimes associated with lower vulnerability levels. This finding suggests that, in the context of energy vulnerability, the predictions of the resource curse theory may not be observed in every case.

    Measuring Sustainability Under Uncertainty: Introducing Net ESG (N-ESG) Performance
    (Wiley, 2025) Ongan, Serdar; Isik, Cem; Aydin, Rahman; Imamoglu, Ilyas Kays; Alvarado, Rafael; Ahmad, Munir
    This study examines the reliability of environmental, social, and governance (ESG) scores in uncertain environments by introducing a new indicator, Net ESG (N-ESG), for the first time. This new index was calculated by subtracting a new ESG-based sustainability uncertainty index (ESGUI) from ESG scores. This study employed Pedroni (2004) and Westerlund (2007) tests, as well as the DOLS method, for 12 developed countries from 2002 to 2020. It analyzed the impact of economic, geopolitical, climate, and energy price-related uncertainties on both ESG and N-ESG through eight different models. Empirical findings indicate that a 1% change in CPU, GPR, EPU, and OPU indices increases ESG by 0.048, 0.355, 0.111, and 0.044 units, respectively, while the same rate of change decreases N-ESG by -6.501, -18.756, -8.972, and -8.193 units, respectively. These results can be interpreted as ESG scores may not fully reflect the true performance of companies in times of uncertainty, while N-ESG provides a more accurate representation of sustainability practices. These results suggest that policymakers should focus their sustainability policies not only on increasing ESG scores but also on preserving the true value of ESG by reducing uncertainty effects.

    The environmental, social and governance (ESG) dimensions of corporate social responsibility (CSR) on energy security
    (Taylor & Francis Inc, 2026) Isik, Cem; Ongan, Serdar; Kuziboev, Bekhzod; Imamoglu, Ilyas Kays; Amin, Azka
    This study investigates the impact of corporate social responsibility (CSR) on energy security (ENSEC) for 34 developed countries. It offers a new institutional perspective by linking CSR to ENSEC within the framework of sustainable development. MMQR, PLFC, and DID methods are used for this analysis. The MMQR results indicate that CSR enhances ENSEC across all percentiles (10%-90%) in both aggregate and disaggregated analyses, across the social, environmental, and governance dimensions. Moreover, the PLFC model's findings reveal that CSR promotes ENSEC in aggregate, regardless of income level. However, in the disaggregated estimates from the PLFC model, the social dimension of CSR has no effect on ENSEC, whereas the environmental and governance dimensions continue to have a positive effect on ENSEC. As for the impact of China's energy investment, only China's fossil energy investment ensures ENSEC. These findings provide important policy insights by empirically validating the role of CSR in addressing long-term energy risks.

    The moderating effects of geopolitical risks on sustainable development through economic complexity and renewable energy consumption in 25 oil-producing countries
    (Springer, 2026) Ongan, Serdar; Ozdemir, Dilek; Imamoglu, Ilyas Kays; Isik, Cem
    Conflicts in controlling or using natural resources, arising from geopolitical risks (GPR), which have become a new normal today, can damage natural ecosystems and threaten sustainable development. In this context, GPR can turn the positive impact of supporting independent variables on sustainable development (SD) into a negative one. This research investigates the moderating effects of GPR on SD through renewable energy consumption (REN) and economic complexity (EC) in 25 oil-producing countries with relatively higher oil-reserve-related risks between 2000 and 2021. The panel quantile regression analysis reveals. (i) While using REN individually improves SD in countries with high SD (in the 80th and 90th quantiles), this improving effect turns to a worsening effect due to its interaction with GPR, which shows the moderating impact of GPR. (ii): While EC individually improves SD across all quantiles, these improving effects persist in countries with low SD (in the 10th, 20th, 30th, and 40th quantiles) even when complexity interacts with GPR, showing that GPR has no moderating impact on SD. Therefore, policymakers should investigate why the interaction of REN with GPR worsens SD in highly sustainable countries and redevelop regulatory renewable energy policies accordingly.

    The Role of Women's Entrepreneurship, Unemployment, Global Warming, and Technology in Sustainable Development: Evidence From OECD Countries
    (Wiley, 2025) Isik, Cem; Ongan, Serdar; Gunlu, Ebru; Aydin, Rahman; Imamoglu, Ilyas Kays
    This study examines the effects of women's entrepreneurship, global warming, technological advancements, and unemployment on the achievement of the sustainable development goals (SDGs) across 38 OECD countries. Using country-specific panel causality methods, the analysis reveals significant asymmetries between developed and developing economies. Women's entrepreneurship (FEM) and technology (TEC) demonstrate stronger positive effects in developing countries such as Mexico, Slovakia, and Costa Rica, supporting SDGs 5 and 9. Global warming (SUR) negatively affects both groups, with notable impacts in Belgium, Mexico, and the UK, emphasizing the urgency of SDG 13. Unemployment (UNM) poses greater threats to sustainable development in emerging economies-particularly in Turkey and Latin American nations-while its influence remains limited in advanced countries. These results underscore the heterogeneous nature of SDG progress and suggest that universal, one-size-fits-all policies may fall short. Instead, national strategies should strengthen gender-inclusive entrepreneurship and innovation, while mitigating climate risks and labor market vulnerabilities. This paper presents a novel, multidimensional econometric framework and offers original insights into how interlinked economic, social, and environmental factors influence sustainability outcomes across diverse national contexts.

    The Role of Women's Labor Law and Business Freedom in Achieving Sustainable Development Goals (SDGs) in OECD Countries
    (Wiley, 2025) Isik, Cem; Ongan, Serdar; Isik, Olcay; Aydin, Rahman; Imamoglu, Ilyas Kays
    Business freedom (FR) and women's labor law (WLL) are critical in achieving the SDGs. This research aims to test the effect of these two factors on the SDGs while also considering economic growth and energy efficiency, framing the analysis within the legal, economic, and environmental dynamics of the SDGs holistically. Fourier-augmented PANIC, cross-sectional dependence tests, panel OLS, bootstrap quantile regression, and panel Granger causality tests are applied for this aim. The OLS and bootstrap quantile regression analyses indicate that while FR negatively affects SDG at lower quantiles, these effects turn positive in higher quantiles. This can mean that in countries with high institutional quality, the freedom to do business becomes a tool for supporting sustainable economic development. The WLL has positive effects on SDGs in all quantiles except the 20th quantile. This result clearly shows the decisive role of women's labor rights and legal protections in driving sustainable development. The Granger causality test also supports these results: FR and WLL have a positive Granger causality effect on the SDGs. Additionally, while GDP positively affects SDGs in all quantiles, renewable energy efficiency negatively affects SDGs at low quantiles and has a positive impact at higher quantiles.
